Osu and welcome to K4L!
Regarding the stripes, they are simply there to show a rank between belts. Generally ranks go from 11th kyu (white) to 1st kyu (brown belt with black stripe) then 1st dan. This may of course vary. Let's say you gain red belt at 10th kyu. At 9th kyu, you will gain a blue stripe, meaning you are ranked above red belt, but not yet a blue belt (8th kyu). Many beginners believe that the stripes are less valued than a new belt - this is however not true. I hope that explains it.
Meanwhile, we have a tradition to encourage new members to introduce themselves. So why don't you
create a thread here and tell us a little about yourself?
